Higher end Tubes for Ah Njoe Tjoeb 4000


I have an Ah! 4000 and want to do some tube rolling. Who knows higher quality tubes that they've tried with this cd player? What were your perceptions? Thanks!

Please don't try them. 6ES8 -- not stable and not interchangeable. 7DJ8 -- different heater voltage. Not interchangeable.
You just need to pay up for the NOS tubes
